I've got the feeling that Claude doesn't use its knowledge properly. I often need to ask some things it left out in the answer in order for it to realize that that should also have been part of the answer. This does not happen as often with ChatGPT or Gemini. Specially ChatGPT is good at providing a well-rounded first answer.
Though I like Claude's conversation style more than the other ones.
I wonder if they are goosing their revenue and usage numbers by defaulting to more verbose replies - I could see them easily pumping token output usage by +50% with some of the responses I get back.
I feel similar ever since the 3.7 update. It feels like Claude has dropped a bit in its ability to grok my question, but on the other hand, once it does answer the right thing, I feel it's superior to the other LLMs.
I am personally finding Claude pretty terrible at C++/CMake. If I use it like google/stackoverflow it's alright, but as an agent in Cursor it just can't keep up at all. Totally misinterprets error messages, starts going in the wrong direction, needs to be watched very closely, etc.
I find ChatGPT and Claude really quite good at C.
